TURN-TABLE FOR HORSE-CARS.

SPECIFICATION forming part of Letters Patent No. 305,278, datedSeptember 16, 1884.

Application filed March 10, 1884. (No model.)

T all whom it may concern Be it known that I, CHARLES F. BoLLwIrr, ofNew Orleans, in the parish of Orleans and State of Louisiana, haveinvented a new and Improved Turn-Table for Horse-Cars, of which thefollowing is a full, clear, and exact description. V

The object of my invention is to provide a new and improved turn-tablewhich is so constructed that the driver of the car running on theturn-table can adjust the turn-table in such a manner as to conduct hiscar to any desired exit-tracl ,whioh turn-table is locked, unlocked, andthrown back automatically.

The invention'consists in a turn-table for horse-cars provided with apivoted lockingbolt adapted to engage with catches on the platformsurrounding the turntable, under which locking-bolt a lever for raisingthe same is pivoted, which lever can be shifted by devices which areoperated automatically by the revolving of the turntable, and canbeadjusted so as to lock the turn-table in any desired position. g

The invention also consists in various parts and details andcombinations of the same, as will be fully described and set forthhereinaf ter.

Reference is to be had to the accompanying drawings, forming apart ofthis specification, in which similar letters of reference indicatecorresponding parts in all the figures.

Figure l is a plan View of my improved turn-table for horse-cars, partsbeing broken out and others shown insection. Fig. 2 is alongitudinal'sectional elevation of the same on the line or a, Fig. 1.Fig. 3 is a plan view of the under side of the revolving platform inpart, showing the mechanism for raising the bolt. Fig. 4 is a sectionalview on the line y y, Fig. 3.

The turntable A is provided with a central'pivot, A, which rests onasuitable projection in the middle of a well, 13, in which 5 theturn-table can revolve. On the turntable platform two parallel rails, O,are secured, and difierent tracks D lead to the turn-table fromdifierent directions. On the turn-table platform A an upright tube, E,is. arranged, which is provided at its upper end with a circular flange,E, which is divided into six I parts by radial lines, or into as manyparts as there are tracks crossing the table. Au upright shaft, F,provided at its upper end with a crank-handle,'F, for turning it, isjournaled in the tube E, and on its lower end, and within a recess inthe under side of the platform A,a cog-wheel,G,is rigidly mounted, whichengages with a like cog-wheel, G",

naled in the platform A, which shaft H is provided on its lower end witha wheel at J, having six radial teeth, J, and the shaft H is alsoprovided with an arm, I, projecting from it. The lower end of the shaftH is suitably journaled in a bracket arm or like device secured on thebottom of the revolving platform. On the sides of the well B twice asmany teeth K are arranged as there are teeth J onthe wheel J-in thiscase six. In a radial slot, L, in the turn-table a lever, M, is pivotedat its upper end, which lever is provided at its upper end with atriangular head, M. A bent bolt, N, is pivoted between angle plates N onthe upper surface of the turn-table in such a manner that the bolt cancover the slotL; but the bolt projects beyond theedge of the turn-table,and is adapted to pass into notches in angular locking-plates 1?,secured in the platform around the turntable, which notches or catchesPare of the usual construction. If the outer end or part of the bolt Nis passed into one of the catches l,the turn-table is locked inposition.

Two levers, It-and S, are pivoted to the under side of the turntable insuch a manner that their outer ends will be under the corners or pointsof the triangular head M, and the opposite ends of the said levers arepro vided with weights R and S. From each lever R and S a pin, 1' and s,respectively pro-. jects through an aperture in the turn-table, theupper ends of the said pins r s adjoining the rails, so that they mustbe depressed by the wheels of a car running on the rails. Both of thepins 1' s of the levers It S are held below the upper edge of the railsC by the weights It S when the locking-bolt N rests on the point of thehead M of the lever M, and one below and the other above the rail whenthe said bolt rests on one of the sides of the head of said lever. Achain or rope, T, connected mounted on the upper end of a shaft, H,joi1r- 60 with the platform, passes over a pulley, a, at means,substantially as herein shown and dethe bottom and a pulley, I), at thetop of an uprightstructure or tower, and from the other end of the saidrope or chain a weight, \V, is suspended.

The operation is as follows: The driver runs the car on the turn-table,and then turns the cranlrhandle l on the upper end of the shaft F tothat section of the ilange E correspond ing in number to the track atwhich he wants to run oif the turn-table. The lever M, when the table isnot in use, hangs vertically, and the locking-bolt N rests on the pointof the triangular head, the locking-bolt thus being kept raised anddisengaged from the catches 1 \Vhen the driver has run the car entirelyon the platform, he guides the horse to the right or left, thus causingthe horse to revolve the turn-table, car and all. livery time that oneof the teeth K in the side of the well strikes a tooth, J, of the wheelJ, the wheel J will be revolved the distance of one tooth, and when therails G on the turn-table arrive at those rails by which the ear is torun from the table the shaft H will be turned to such an extent that itsarm I will strike the lever M and swing the same inward and upward,thereby bringing one of the sides of the triangular head M parallel withthe under side of the lockingbolt N, thus permitting the same to dropinto the notch of the corresponding catch, 1?, there by locking theturntable in place. justing the crank-handle F to stand over a subdivision of the ring E corresponding to the number of the track at whichthe car runs off of the turn-table, the wheel J is so adjusted thatbefore the turn-table arrives at the de sired track the wheel J will bestruck by the requisite number of teeth K to bring the arm I into such aposition that it can swing the lever M down, and thus lower theloeking-bolt N and lock the turntable in place. The turntable has nowbeen shifted and locked and the car can run off but it is also necessarythat the turn-table should be swung back again to its normal position.This is accomplished by running the car off of the turn-table. When thecar runs off, the last wheel strikes either one of the pins 1' or s,owing to the direction the car approaches the table, thereby swingingthat end of the corresponding lever under the end of the triangular headM upward, and

thus causing it to swing that end of the triangular head that has beenlowered upward, whereby the point of the head M" will raise thelocking-bolt N out of the catch P, and thereby release the turn-table.Then as soon as the turntable is released the weight V deseends andpulls the turn-table back into its former position, ready for the nextcar, and so on.

Having thus described my invention, I claim as new and desire to secureby Letters Patent 1. The combination, with a turn-table for horse-cars,of means for automatically locking the turn-table after it has turned acertain distance, and ofa device for adjusting the said.
